An assessment of antimicrobial resistant disease threats in Canada.

ABSTRACT:

Background

Antimicrobial resistance (AMR) of infectious agents is a growing concern for public health organizations. Given the complexity of this issue and how widespread the problem has become, resources are often insufficient to address all concerns, thus prioritization of AMR pathogens is essential for the optimal allocation of risk management attention. Since the epidemiology of AMR pathogens differs between countries, country-specific assessments are important for the determination of national priorities.

Objective

To develop a systematic and transparent approach to AMR risk prioritization in Canada.

Methods

Relevant AMR pathogens in Canada were selected through a transparent multi-step consensus process (n=32). Each pathogen was assessed using ten criteria: incidence, mortality, case-fatality, communicability, treatability, clinical impact, public/political attention, ten-year projection of incidence, economic impact, and preventability. For each pathogen, each criterion was assigned a numerical score of 0, 1, or 2, and multiplied by criteria-specific weighting determined through researcher consensus of importance. The scores for each AMR pathogen were summed and ranked by total score, where a higher score indicated greater importance. A sensitivity analysis was conducted to determine the effects of changing the criteria-specific weights.

Results

The AMR pathogen with the highest total weighted score was extended spectrum B-lactamase-producing (ESBL) Enterobacteriaceae (score=77). When grouped by percentile, ESBL Enterobacteriaceae, Clostridium difficile, carbapenem-resistant Enterobacteriaceae, and methicillin-resistant Staphylococcus aureus were in the 80-100th percentile.

Conclusion

This assessment provides useful information for prioritising public health strategies regarding AMR resistance at the national level in Canada. As the AMR environment and challenges change over time and space, this systematic and transparent approach can be adapted for use by other stakeholders domestically and internationally. Given the complexity of influences, resource availability and multiple stakeholders, regular consideration of AMR activities in the public health realm is essential for appropriate and responsible prioritisation of risk management that optimises the health and security of the population.

Project description:INTRODUCTION:This protocol will guide and explain the working process of a systematic scoping review on vulnerability assessment tools in the field of infectious disease outbreaks and antimicrobial resistance (AMR) crises. The scoping review will appraise existing tools or methodologies to identify local level vulnerabilities in the context of infectious disease outbreaks and AMR. Due to this focus on infectious threats and AMR, the review also considers articles using a 'One Health' approach to assess the vulnerability of individuals, groups and practices in human-animal-environment interactions. Given the broad nature of vulnerability, we aim to allocate studies discerning the process of identifying vulnerable or at-risk groups during a crisis, instead of studies taking vulnerability only as a starting point. Because considerable research has been conducted on vulnerability, disasters and climate change, we will also assemble tools developed from these fields. To our knowledge, this is the first planned systematic scoping review of vulnerability assessment tools for disease outbreaks and AMR, taking into account practices at the human-animal-environment interface that can lead to increased risk of exposure of individuals to infections, pathogen spillovers or epidemics. METHODS AND ANALYSIS:To develop the protocol, we used the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols checklist (PRISMA-P 2015) in compliance with the PRISMA Extension for Scoping Reviews Explanation and Elaboration. With the assistance of an experienced research librarian, we developed the search strategy, which targeted the following databases: Medline, Global Health database, Web of Science and Embase. A second strategy was developed for Epistemonikos, African Journals Online and Global Index Medicus because these databases do not provide the infrastructure for an advanced search. We consider studies published between 1978 and 2019 and include articles, book chapters, websites and grey literature from selected non-governmental organisations and non-profit organisations working in the health field. We contact them directly regarding whether they are working with or have developed a vulnerability assessment tool. To address the dynamic nature of our investigation, we develop a flow diagram which we continually update to reflect the selection process. Two reviewers (MJ and LL) independently screen the literature and resolve conflicts through discussion rounds. Data extraction will be conducted by four researchers (MJ, LL, EJ and RK) through inductive and deductive coding. Extracted data will be systematically compared and divergences highlighted. ETHICS AND DISSEMINATION:Ethical approval is not required because this study does not involve collection of primary data. The purpose of this review is to disseminate a catalogue of vulnerability assessment tools and a brief summary of key results and recommendations for SoNAR-Global partners in Bangladesh, Ukraine and Uganda. The catalogue will be made publicly available. On the basis of our results, SoNAR-Global partners will pilot one of these tools.

Project description:BackgroundFew studies have assessed the relationship between poverty and the risk of infection with antimicrobial resistant organisms (AROs). We sought to identify, appraise, and synthesize the available published Canadian literature that analyzes living in poverty and risk of AROs.MethodsA structured narrative review methodology was used, including a systematic search of three databases: MedLINE, EMBASE and Web of Science for articles pertaining to poverty, and infection with AROs in Canada between 1990 and 2020. Poverty was broadly defined to include economic measures and associated social determinants of health. Based on inclusion and exclusion criteria, there were 889 initial articles, and 43 included in the final review. The final articles were extracted using a standard format and appraised using the Joanna Briggs Institute Levels of Evidence framework.ResultsOf 43 studies, 15 (35%) related to methicillin-resistant Staphylococcus aureus (MRSA). One study found a 73% risk reduction (RR 0.27, 95%CI 0.19-0.39, p = < 0.0001) in community-acquired MRSA (CA-MRSA) infection for each $100,000 income increase. Results pertaining to homelessness and MRSA suggested transmission was related to patterns of frequent drug use, skin-to-skin contact and sexual contact more than shelter contact. Indigenous persons have high rates of CA-MRSA, with more rooms in the house being a significant protective factor (OR 0.86, p = 0.023). One study found household income over $60,000 (OR 0.83, p = 0.039) in univariate analysis and higher maternal education (OR 0.76, 95%CI 0.63-0.92, p = 0.005) in multivariate analysis were protective for otitis media due to an ARO among children. Twenty of 43 (46.5%) articles pertained to tuberculosis (TB). Foreign-born persons were four times more likely to have resistant TB compared to Canadian-born persons. None of the 20 studies used income in their analyses.ConclusionsThere is an association between higher income and protection from CA-MRSA. Mixed results exist regarding the impact of homelessness and MRSA, demonstrating a nuanced relationship with behavioural risk factors. Higher income and maternal education were associated with reduced ARO-associated acute otitis media in children in one study. We do not have a robust understanding of the social measures of marginalization related to being foreign-born that contribute to higher rates of resistant TB infection.

Project description:ImportancePatient disclosure to their clinician about experiencing an imminent threat is a critical step toward receiving support or assistance.ObjectiveTo examine the frequency of patients not disclosing their experience of imminent threats to their clinician and their reasons for doing so.Design, setting, and participantsSurvey study incorporating results from 2 national, nonprobability samples of 2011 US adults recruited from Amazon's Mechanical Turk (MTurk) from March 16 to 30, 2015, and 2499 recruited from Survey Sampling International (SSI) from November 6 to 17, 2015. Data analysis was conducted from December 20 to 28, 2018.Main outcomes and measuresSelf-reported nondisclosure of 4 types of imminent threats (depression, suicidality, abuse, and sexual assault) to their clinician and reasons for nondisclosure.ResultsThere were 2011 participants in the MTurk sample (1210 [60.3%] female; 1696 [60.2%] white; mean [SD] age, 35.7 [12.4] years; age range, 18-79 years) and 2499 participants (1273 [51.0%] female; 1968 [78.8%] white; mean [SD] age, 61.0 [7.6] years; age range, 50-91 years) in the SSI sample. Among those who reported experiencing at least 1 of the 4 imminent threats, 613 of 1292 MTurk participants (47.5%) and 581 of 1453 SSI participants (40.0%) withheld information from their clinician. The most commonly endorsed reasons for withholding this information included being embarrassed (MTurk: 72.7%; SSI: 70.9%), not wanting to be judged or lectured (MTurk: 66.4%; SSI: 53.4%), and not wanting to engage in a difficult follow-up behavior (MTurk: 62.4%; SSI: 51.1%). Respondents who experienced at least 1 of the 4 imminent threats had significantly higher odds of nondisclosure in both samples if they were female (MTurk: odds ratio [OR], 1.66 [95% CI, 1.30-2.11]; and SSI: OR, 1.33 [95% CI, 1.07-1.67]) or younger (MTurk: OR, 0.99 [95% CI, 0.98-1.00]; and SSI: OR, 0.98 [95% CI, 0.97-1.00]). Worse self-rated health was also associated with nondisclosure, but only in the SSI sample (OR, 0.85 [95% CI, 0.74-0.96]).Conclusions and relevanceThis study suggests that many people withhold information from their clinicians about imminent health threats that they face. A better understanding of how to increase patients' comfort with reporting this information is critical to allowing clinicians to help patients mitigate these potentially life-threatening risks.

Project description:In recent years, vegetables gain consumer attraction due to their reputation of being healthy in combination with low energy density. However, since fresh produce is often eaten raw, it may also be a source for foodborne illness. The presence of antibiotic-resistant bacteria might pose a particular risk to the consumer. Therefore, this review aims to present the current state of knowledge concerning the exposure of humans to antibiotic-resistant bacteria via food of plant origin for quantitative risk assessment purposes. The review provides a critical overview of available information on hazard identification and characterization, exposure assessment, and risk prevention with special respect to potential sources of contamination and infection chains. Several comprehensive studies are accessible regarding major antimicrobial-resistant foodborne pathogens (e.g., Salmonella spp., Listeria spp., Bacillus cereus, Campylobacter spp., Escherichia coli) and other bacteria (e.g., further Enterobacteriaceae, Pseudomonas spp., Gram-positive cocci). These studies revealed vegetables to be a potential-although rare-vector for extended-spectrum beta-lactamase-producing Enterobacteriaceae, mcr1-positive E. coli, colistin- and carbapenem-resistant Pseudomonas aeruginosa, linezolid-resistant enterococci and staphylococci, and vancomycin-resistant enterococci. Even if this provides first clues for assessing the risk related to vegetable-borne antimicrobial-resistant bacteria, the literature research reveals important knowledge gaps affecting almost every part of risk assessment and management. Especially, the need for (comparable) quantitative data as well as data on possible contamination sources other than irrigation water, organic fertilizer, and soil becomes obvious. Most crucially, dose-response studies would be needed to convert a theoretical "risk" (e.g., related to antimicrobial-resistant commensals and opportunistic pathogens) into a quantitative risk estimate.
